RAIL-JOINT.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed March 4, 1916. Serial No. 82,163.

To all whom it may concern:

Be it known that I, J AMES T. MARSHALL, a citizen of the United States, residing at Haughton, in the parish of Bossier and State of Louisiana, have invented certain new and useful Improvements in Rail- Joints, of which the following is a specification, reference being had to the accom panying drawings.

This invention relates to certain improvements in rail joints and it is an object of the invention to provide a joint of this char acter having novel and improved means whereby the meeting ends of rails are effectively held against pounding as the rolling stock passes thereover, and whereby spreading of the rails is prevented.

It is also an object of the invention to provide a novel and improved rail joint including angle bars coacting with the meeting ends of rails with the upper edges of said plates disposed on an arch with the arches thereof fitting under the balls of the rails at the meeting ends thereof, whereby pounding is prevented and whereby the rails are maintained in proper alinement.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved rail joint whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein Figure l is a view in top plan illustrating a rail joint constructed in accordance'with an embodiment of my invention; Fig. 2 is a view in elevation of the outer side of my improved rail joint; Fig. 3 is a view in bottom plan of one of the tie plates herein included; Fig. 4. is a view in bottom plan of a second tie plate herein employed; Fig. 5 is a sectional view taken substantially on the line 55 of Fig. 2; and Fig. 6 is a sectional view taken substantially on the line 66 of Fi 2.

is disclosed in the accompanying drawings, RR denote the meeting ends of rails and T and T denote the tie plates or angle and, as is particularly illustrated in Fig. 2,

it is to be observed that the upper edges of the tie plates or angle bars T and T are arcuate with the arches thereof underlying and contactinguwith the balls of the rails at their meeting ends. This arrangement in actual practice has been found of especial importance as it has been clearly demonstrated that this construction serves to prevent the joint from hammering down and to keep the track level, whereas with the upper edges of the plates straight a dip soon forms in the angle bars or plates.

As herein disclosed, the plates T and T are so formed as to cont-act with the web of the rails. and to overlie the base flanges thereof, and the eiiiciency of my joint has been materially increased by having the base portion 1 of each of the plates arranged on arches substantially concentric to the upper edges thereof.

As is particularly disclosed in Figs. 5 and 6, it is to be noted that the bases 1 of the plates or angle bars T and T extend beyond the flanges of the rails and have the intermediate portion thereof positioned beyond the flanges of increased thickness with the inner margin of said thickened portion 2 provided with the depending webs or trusses 3, whereby the tie plates or angle bars T and T are materially strengthened. The plate or angle bar T is provided with thelateral extensions 4. at the opposite ends thereof and with the chairs 5 underlying the rails and the extended portion of the plate or angle bar T, said chairs 5 being provided the openings 7 produced in the extended portion of the plate T and through which anchoring spikes or the like are directed and engaged with the ties of a roadway. The lateral extensions 4 are also provided with the spike openings 8. arranged as particularly shown in Figs. 1 and 3. The extensions t and the verticalportion of the plate or angle bar T have integrally formed therewith the brace plates 9 arranged on a predetermined incline and whereby it will be perceived that the rails R are effectively held against turning over and also effectively prevented against spreading. It is also to be understood that the vertical portions of the plates or angle bars T and T i are provided with suitable openings through said openings in the plates being in register with suitable openings formed in the webs of the rails.

From the foregoing description, it is thought to be obvious that a rail joint constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason. I do not wish. to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in prac-, tice.

I claim:

1. In combination with. the meeting ends of rails, said meeting ends being straight, splice plates coacting therewith and interposed between the flanges of the rails and the balls thereof, the upper edges of the plates being arcuate with their arches arranged at the meeting ends of the rails and contacting with the under surfaces of the balls, said plates also overlying the flanges of the rails and having said overlying flanges arcuate and substantially concentric to the upper edges of the plates, the extremities of the overlying portions of the plates contacting with the flanges of the rails and the intermediate portion being free therefrom.

2. In combination with the meeting ends of rails, said meeting ends being straight, splice plates coacting therewith and interposed between the flanges of the rails and the balls thereof, the upper edges of the plates being arcuate with their arches arranged at the meeting ends of the rails and contacting with the under surfaces of the balls, said plates also overlying the flanges of the rails and having said overlying flanges arcuate and substantially concentric to the upper edges of the plates, the extremities of the overlying portions of the plates contacting with the flanges of the rails and the intermediate portion being free therefrom, the outer mar inal portions 01"" the plates being or increased thicknesses, the inner margins of said thickened portions being provided with depending webs. In testimony whereof I hereunto atlix my signature in the presence of two witnesses.
